CH. Ill] MAGIC LANTERNS WITH MAZDA LAMPS 91 FIG. 52. SIMPLE MAGIC LANTERN WITH INCANDESCENT LAMP AS RADIANT. (Cut loaned by Williams, Brown & Earle). This is known as the "Society Incandescent Lantern No. 3 G." It is especially designed for use with permanently mounted lantern slides (fig. 15). § 138. Centering and distance from the condenser. — The centering along one axis is as with the arc lamp (§ 51). In general the concentrated filament should be at the principal focal distance from the condenser. One can determine the best position by the use of a good lantern slide and changing the distance of light and condenser until the best position is found. It is well to mark that position for future use. FIG. 53. MAGIC LANTERN WITH MAZDA LAMP. (Balopticon B.; Cut loaned by the Bausch 6" Lornb Optical Co.}. This lantern can be used with the small arc lamp on the house lighting system, with the Mazda incandescent lamp or with acetylene.
